'CHIME swrrc'n.

Original application filed October 10, 1921, Serial .No. 506,673. Divided and this application filed February 9, 1925.

To all whom it may concern:

Be it known that I, ARTHUR S. BOEHM, a citizen of the United States, residing at Baltimore and State of Maryland, have invented certain new and useful, Improvements in Chime Switches; and I do declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it appertain's to make and use the same.

My invention relates to improvements in electric switches designed primarily for controlling elec'trical church and cathedral chimes, the present application being a division of my U. S. application, Serial No.

506,673, filed Oct. 10, 1921. I

The principal object is to provide a novel controlling switch for thesounding means of each chime, including two separately movable keys associated with each other in much the same manner as the usualblack and white keys of a piano or like instrument, the arrangement being such that when the longer key is depressed, the chime will be sounded loudly while depression of the short key will cut in a resistance and thus softly sound the chime.

Another object is to make novel provision for preventing arcing between the contacts of the controlling switch, when said contacts are separated.

With the foregoing in View, the invent-ion resides in the novel subject matter hereinafter described and claimed, the descriptive matter being supplemented by the accompanying drawing.

Figure 1 is a diagrammatic view showing the switch associated with electrical operating means for one of the chime-playing levers of an ordinary console.

Figure 2 is an enlarged longitudinal sectional view through the controlling switch, parts being in elevation.

Figure 8 is a top view of the switch.

Figure 4 is a vertical transverse sectional view as indicated by line 44 of Fig. 2.

In the drawing above briefly described, I have illustrated the switch in connection with a means which may be employed for operating one of a series of chimes, but it is to be understood that this arrangement may be duplicated for all of the chimes and the keys of the several switches assembled on a keyboard, ten keys being usually sufficient although any suitable number may Serial No. 8,046.

be used. It may be further explained that whereas the usual console or chime playing mechanism, is commonly located in a story of the church or the like, near the belfry, the controlling switches of my invention may be located onthe main floor, so that much more cooperation may be had between the operator of the chimes and the persons conducting the ceremony, service or the like.

In the drawing, the numeral 1 designates one of the well known playing levers of an ordinary console, which lever is connected by a ropeor cable 2 with a clapper 3 of a chime 4. Beneath the lever 1, a solenoid 5 is shown, whose core 6 is connected as at 7 with the lever 1. The passage of electrical current (either alternating or direct) through the solenoid 5 and the-action of the core are controlled by a key-switch constituting the present invention. This switch is designated in a general way by the reference character 8. ence to a switch base ofinsulating material fromwhich a bifurcated standard 10 rises, said standard having a pivot bolt 11 upon which relatively long and short keys 12 and 13 respectively, are pivotally mounted. The longer key 12 is formed with a longitudinal recess or slot 14 within which received, so as to not only produce a compact arrangement, but to locate both the loud and soft keys in such proximity to each other that they may be selectively used at will.

At one end, the keys 12 and 13 carry adjustable stop screws 15 which are normally held in contact with a stop plate 16 on a support 15 rising from the base 9, by means of coiled springs 17 connected to the keys and base. These springs serve to normally move the keys in such a manner as to separate the movable contacts 18, carried there by, from fixed contacts 19 which are secured upon the base 9.

One form of wiring which may be used is shown in diagram, the numeral 20 having reference to a wire which extends from one terminal of the solenoid coil and is in electrical engagement with both of the contacts 18. The numeral 21 designates a wire leading to the other terminal of the solenoid coil, from any appropriate source of electrical supply, a return wire 22 is shown leading from the contact 19 of the relatively long key 12, while a shunt wire 23 leads the key 13 is The number 9 has referfrom the other contact 19to the wire 22 land is equipped With a resistance coil 24:. -Bythis Wiring, When the key12 is depressed,

A meager f thefor'm th current travels thrmigh the. s l noidfiqi with full'force and thereby sounds the chime 4 rather loudly. When the key 13 ciswdepressed however, the current necessarily flows through" the resistance 24 so that t-he core 6 of the solenoid is afiected to a smaller de r e, w h the ,ra a th hime is which .is
